Yanmar Battery Water Level Bypass
Time Required - 30 Minutes Special Tools ---- Soldering iron recommended
A lot of the imported Yanmars came standard with batteries that have internal water (electrolyte) level switches in them. Most of the US batteries do not have these switches. When you replace the factory battery with an aftermarket battery you will usually end up with a light ( usually a picture of a battery with little waves in it) that is telling you your battery is low on water.
What you will need:

Locate the water level plug in the wiring harness that goes to the headlights around the area of the battery. On most Yanmar tractors it should be a plug with two contacts in it. Take a jumper wire and connect the two contacts and see if the "low battery water" light goes off. If not you either have an unusual system or there is another problem.
